The Natural User Interface

The NUI (Natural User Interface) for the 2D GUI must recognize and trace the captured 3D image to transform to the UI event(s) first, but I don't care about that because I only do the 3D VR/AR UI. The NUI in the 3D VR/AR UI just directly maps the captured 3D image to the virtual reality to become the model added in it then lets themselves interact, so it is not necessary to have the event processing. In the 3D AR/VR UI, the pattern recognition and trace only occurs in the 3D AR/VR space.
